Problems solved by technology

However, when the components are made of different types of materials, it can be difficult to provide a uniform visual appearance of the article when the components are assembled.
Such use of multiple specialized coatings and pigments may result in relatively complex and costly manufacturing processes, inventory issues and may also gives rise to the need to “color match” the different coatings.
While color matched components may have substantially the same appearance in some viewing and illumination conditions, they may not maintain the same appearance when the viewing angle is changed, when the spectral distribution of the light source is changed and / or when the coatings have aged.

example 1

[0058] An aqueous color harmonization coating composition was made and applied to athletic shoe components comprising different materials as follows. A polyurethane dispersion was made by charging a reaction vessel equipped with stirrer, thermocouple, condenser and nitrogen inlet with 1447.3 g polytetramethylene ether glycol having a molecular weight of about 1,000 sold under the designation TERATHANE 1000, 145.4 g dimethylolpropionic acid and heated to 60° C. 965.3 g isophorone diisocyanate was added over 13 minutes followed by 637.5 g methyl ethyl ketone and 4.34 g dibutyltin dilaurate. The reaction exothermed to 72° C. The reaction temperature was raised to 80° C. and the contents were stirred until the isocyanate equivalent weight was 923.5. Then 114.0 g dimethylolpropionic acid was added to the reaction flask. The contents were stirred until the isocyanate equivalent weight was 1430.2.

Abstract

Color harmonization is provided for articles of manufacture comprising different substrate materials. A coating composition is selected that can be applied to the different substrate materials while maintaining substantially uniform visual characteristics of the article. The substrates may include flexible materials such as natural leather, synthetic leather, vinyl, foam, textiles and the like. Examples of articles of manufacture include footwear, automotive upholstery and automotive interiors.

Description

FIELD OF THE INVENTION [0001] The present invention relates to color harmonization, and more particularly relates to the use of a coating composition that provides substantially uniform visual characteristics for articles of manufacture comprising different types of substrate materials. BACKGROUND INFORMATION [0002] Many articles of manufacture are made from different types of components that are assembled together. It is often desirable to maintain color uniformity among the various components. However, when the components are made of different types of materials, it can be difficult to provide a uniform visual appearance of the article when the components are assembled. [0003] For example, footwear such as athletic shoes often comprise different types of materials including natural leather, synthetic leather, vinyl, fabric, foam and rubber. A different coating composition is conventionally applied to each type of substrate material. For example, one type of coating may be applied ...
